Crystal structure of the dimeric unswapped form of bovine seminal ribonuclease
Overview
Bovine seminal ribonuclease is a unique case of protein dimorphism, since, it exists in two dimeric forms, with different biological and kinetic, behavior, which interconvert into one another through three-dimensional, swapping. Here we report the crystal structure, at 2.2 A resolution, of, the unswapped form of bovine seminal ribonuclease. Besides completing the, structural definition of bovine seminal ribonuclease conformational, dimorphism, this study provides the structural basis to explain the, dependence of the enzyme cooperative effects on its swapping state.
